SYSML21 — Incorrect model snippets explaining semantics of Rendering Usages

In subclause 8.4.22.6 on semantics of Rendering Usages the model snippets under bullets 2 and 3 contain mistakes.

Under bullet 2 in the qualified names Renderings:: should be replaced with Views::. Also in the third line view should be replaced with rendering so that the snippet reads:

rendering def Rnd specializes Views::Rendering {
    ref rendering rnd1 subsets Views::renderings;
    rendering rnd2 subsets Views::Rendering::subrenderings;
}

Under bullet 3 view def vr should rather be a view usage view vr, so that the snippet reads:

rendering r1;
rendering r2;
view def VR specializes Views::View {
    render r1 redefines Views::View::viewRendering;
}
view vr : VR {
    render r2 redefines VR::r1;
}

Also, it would help the reader to explain that the model snippets explicitly show subsets resp. redefines relationships that are implied and typically left out.
